Why was Jenny's strip club nudity necessary?

Okay, I am not a huge prude when it comes to nudity in film. I realize there are a lot of films where it serves a purpose. I would prefer it not be in films at all, but I can easily tolerate it if it isn't gratuitous or there was some purpose to it. I realize that Jenny's nudity in the strip club scene was very limited and was probably one of the most tame nude scenes ever, but I find it also to be one of the most disturbing and unnecessary nude scenes in any film ever. Let me explain.....

1) Forrest Gump is a family film. Everybody has seen it. It is very popular. This movie would have been just as good minus the nudity. Next time you watch Forrest Gump, and you get to the strip club scene, think about how much of a family film this is, and the nudity in that scene will seem over the top and a little too much when thinking in that context. It is not like this is an R rated film that has nude women as one of its main themes.

2) Why was it necessary for us to see Jenny's bare butt during this scene? The previous stripper who is on stage before her is wearing a full bikini bottom and it is implied she is topless but we don't see anything. That is all that is necessary to get the point across in a family film like this. It was obvious to us that Jenny was topless and covering herself with a guitar. But they had to go further and show us that shot from behind showing part of her thong "covered" butt crack sitting on a stool. That shot was way too long by the way. But then that wasn't enough . They had to show us her entire bare butt in another scene when she is storming off the stage. I can understand that maybe they wanted to show us she was in only a thong to show her vulnerability in this scene which is fine. But we got the point already when they showed the behind shot when she was still sitting and singing. Why was the next scene where she storms off the stage necessay? Not only do we see more of her butt here in a gratuitous manner, but we see a lot of side boob, plus she is standing up and walking here while appearing to be completely naked if your eyes miss the flesh colored thong. Way too gratuitous for a family film.

3) In the Alabama football shower room scenes they go through great lengths to make sure no male bare butts are shown in the background. Also, when Forrest has a bandaged butt later, we see a quick fuzzy glimpse of his crack. It is obvious that this movie was careful to hide any male butt nudity. So why did we get a nice long look at Jenny's butt earlier?

4) Because of what I mention in points 1 and 3 especially, I have always felt sorry for this actress and I have always wondered if she was pressured into doing that scene only to regret it later. This actress has stated publicly that she doesn't like nude scenes and I have noticed that her other nude scenes are very quick and tasteful and tend to be limited to obscure movies that most people won't see other than a small percentage of women. Forrest Gump has shown her bare butt to the entire world for no reason. Also , I really hope they respected her privacy during shooting that scene. During the part where she storms off the stage naked you only see the heads of four men in the audience so I really hope most of the room was cleared out when she had to get off the stool and walk naked.

5) Jenny was abused as a child. By showing her naked body as an adult is seems they are putting the joke on her instead of her father. Just seems disturbing and exploitative in my opinion.
